MECHANlCAL MUSlCAL iNSTRUMENR SPECIFICATION forming part of Letters Patent No. 293,184, dated February 5, 1884.

Application filed Xovember 6, 1877.

To all whom it may concern:

Be it known that I, NnwimNR. Mxnsnnix, of New York, in the county of New York and State of NewYork, haveinvented certain new and useful Improvements in Musical Instruments, of whichthefollowingisa specification.

My invention consists in the combination, in a mechanical musical instrument, of a se ries of sound-producing devices, a rest provided with openings, a music-sheet traveling over said rest and controlling the operation of said sound-producing devices, and a cap or presser arranged immediately over said rest and holding the music-sheet thereto. The cap or presser is preferably provided with apertures extending between its exterior and the music-sheet, and it is also preferably capable of being moved toward and from the rest, and combined with springs for impelling it toward the rest and holding it against the musicsheet.

It also consists in the combination, in a mechanicalmusical instrument, of sound-producing devices, a rest provided with openings, a music-sheet traveling over said rest and controlling the operation of said sound-producing devices, and a cap or presser arranged immediately over said rest and bearing upon said music-sheet opposite partitions between the said openings, whereby the music-sheet is held to the rest.

It also consists in the combination, in a mechanical musical instrument, of sound-producing devices, a rest provided with openings, a music-sheet traveling over said rest and controlling the operation of said soundproducing devices, and a cap or presser arranged immediately over said rest and bearing upon said music-sheet opposite a portion of said rest at the front and rear of said openings, whereby the music-sheet is held to the rest.

It also consists in the combination, in a meehanical musical instrument, oi'sound-producing devices, a rest provided with openings, a music-sheet traveling over said rest and controllingthe operation of said sound-producing devices, a cap or presser arranged immediately over said rest and holding the musicsheet thereto, and guiderails for said musicsheet.

It also consists in the combination, in ame chanical musical instrument, of reeds, chambers containing said reeds, air-ducts communicating with said chambers on one side, transverse openings communicating with the said chambers at the opposite side, but out of line with said air-ducts, and a perforated musicsheet acting as a valve, whereby the passage of air through said openings is controlled, the reeds and the music-sheet, as it travels, being approximately parallel.

It also consists in the combination, in a mechanical musical instrument, of a rec'd, a reedchamber, an air-duct communicating with one side of said chamber, a transverse opening communicating with the opposite side of said chamber, but out of line with the said airduct, and a slide-valve for controlling the pas sage of air through said opening, operating upon said opening in plane parallel with the said reed.

It also consists in a mechanical musical instrument having a cap or presser held against a music-sheet in proximity to the reed-ducts by spring-pressure.

In the accompanying drawings, Figure 1 is a longitudinal section through an instrument embodying my invention. Fig. 2 is a side elcvation, showing the mechanism which open ates the bellows; and Fig. 3 is aplan view, representing the instrument with the musiesheet on it.

A represents the case, which may be made .in any form or after any suitable design.

B is the receiver.

O G are bellows, (here represented as constructed upon the exhaust principle,) and D the wind-chest.

E is the tube-board or reed-chest, containing the sound-producing devices, (shown as consisting of reeds a, which are here repre sented as arranged in an approximately-horizontal posit-ion.) The reed-chest E communicates with the wind-chest D by means of airducts 0 under the reeds a, and is constructed with openings 0, for the passage of air to effect the operation of the reeds a, and the said openings 0 are transverse to the reeds (t and out of line with the air-ducts 0, so that air ing through them will impinge upon the reeds throughout a great extent, passin obliquely through the reeds from the openings 0 to the ducts o. The top of the reed-chest, which is RSS- elevated slightly above the top board of the case, is approximately parallel with the reeds a, and serves as a rest for the traveling musicsheet H, which also travels in a plane parallel with the reeds and acts as a slide-valve for controlling the passage of air through the opening 0 in the -reedchest E, for operating the reeds.

e eedesignate feed-rollers, preferably covered with rubber, for producing the travel of the music-sheet H. The music-sheet passes between these feed-rollers, and to permit of this, without causing the rollers to lift the sheet off the rest, they are arranged with their meeting surfaces above the top board of the instrument and approximalely in the same plane as the top of the rest, as shown clearly in Fig. l. The upper roller, 6, is shown as having at one end a crank provided with a handle, G, whereby it may be operated, and thus constitute the driving-shaft of the instrument. At the other end is another crank, J, engaging with a slot in a bellows-operating or pump lever, F, and through rods f f transmitting motion to the bellows O C. The other roller, 0, is represented as having a spring, for pressing it upward tightly against the mu sic-sheet. The lower feed-roller, e, is rotated by friction when the music-sheet H is between the rollers e e,- and it will therefore be seen that the upper feed-roller, c, constitutes a shaft for operating thelower feed-roller as well as the bellows G O.-

I designates a cap or presser, arranged immediately over the rest in proximity to the reedducts, for holding the music-sheet H tightly against the rest. This cap or presser is provided with apertures or passages between its exterior and the-music-sheet for the passage of air to the openings 0 in the reedchest to operate the reeds a. The cap or presser I is fitted between guide-rails c cone at each side of the instrumentwhich furnish guides for the traveling music-sheet H. 'The cap or presser I, as will be clearly seen in Fig. 1, is arranged to bear upon the musicsheet in front and in rear of the openings 0 in the rest, and also opposite the partitions between said openings, and the said cap or presser is capable of being moved toward and from the rest, such movement being here provided for by furnishing said cap or presser with pivots m, whereby it is pivoted in the guiderails c 0. These pivots m are elevated considerably above the rest, and the under side of the cap or presser adjacent to them is chamfered off, so that when the cap or presser is turned upward sufficiently to bring its chamfered portion parallel with the rest E, considerable space will be afforded between it and the rest. The cap or presser is impelled downward toward the music-sheet by springs b, which are attached to the guide-rails c by screws 0, which provide for turning the springs into a position parallel with the guide-rails 0 when it is desired to turn the cap or presser I upward upon its pivots. IVhen the springs b are turned so as to rest upon the cap or presser, they rest in grooves or recesses b in said cap or presser, and are thereby held against accidental displacement. The springs b impel the cap or presser toward the rest, so that it will always exert a yielding pressure on the music-sheet. The music-sheet H passes under the spring cap or presser I, and when the handle G is turned isdrawn between the rollers e e, the bellows meanwhile being operated by the crank J, the lever F, and rods f f. The spring-actuated cap or presser I serves to keep the music-sheet H under the influence of the wind,which forces it closely to its seat or rest, so that there shall be no leak.

The bellows or feeders O O are operated alternately, and thus a gradual exhaust force is exerted upon the receiver B, which provides for an even supply of air.

It will be observed that the lever F and rods f f are both arranged at one side of and beyond the range of the reeds a and of the path traveled by the music-sheet H.

The music-sheet H in Fig. l is represented as having its two ends joined together so as to form an endless band, for the purpose of repeating the tune as often as desired.
